Be itknown-'that I, I'SAIA'H B. CoLuMAN, of 'Detroit, inlthe county ofWayneand State of Michigan,

i have invented a new. `useful Improvement. in Steam- Traps; andI doherebydeclare that the following is a full, clear, and exact descriptionthereof, which will 4 enable others skilled in `the art to make and usethe j saine, reference being haA to the accompanying drawan'dwater-traps, an'djconsists iu combningapair ot' Vpointedcentering-pinswith the shaft of the trap, and the other partsusuailyappertaining thereto, to prevent sticking or frictional pressure.
